* Fix text-file-busy error when running the binary by replacing the use
of named temp file with simply using the input source file and the

* Fix hard-coded library dependencies by sharing code with the cmake
xtask that needs the same list.
This extracts a compiler command line from the cc crate, runs the
compiler and tries to run the resulting binary. Unfortunately the latter
fails still.
